Definitions

  • the present invention relates on the one hand to a method for the treating of products, such as eggs to be hatched, with a conditioned gas stream, which method is carried out in a climate chamber, and relates on the other hand to a climate chamber for implementing this method.
  • the climate chamber comprises:
  • ⁇ a substantially closed compartment having two opposing lateral walls provided with one or more passages
  • ⁇ a substantially closed channel which extends around the outside of the compartment and connects one of said lateral walls to the other of said lateral walls in order to form together with the compartment a substantially closed circuit; and the gas stream is circulated through the circuit.
  • the term "uniform treatment of each product” refers in the present case to the fact that the product to be treated is treated uniformly on all sides.
  • this is particularly important with regard to the temperature. It has been found that the temperature of hatching eggs at the side where the air stream flows in, known in sailing terminology as the weather side, differs somewhat from the temperature at the side positioned in the shadow of the inflow side, known in sailing terminology as the lee side.
  • the Applicant has found that these small differences in temperature adversely affect the development of the embryo. Particularly in the very early phase of development of the embryo, especially during the first 4 to 10 hours, this has been found to have a relatively marked influence.
  • the entire initial period of the hatching of the eggs is very important for the development of the embryo.
  • the Applicant expects these problems also to affect other products.
  • a specific treatment such as a gas assembly.
  • a gas is often added to influence the ripening process. If the gas assembly does not then access all sides of the product uniformly, the product will not ripen uniformly.
  • the object of the present invention is therefore to improve the method according to the preamble of Claim 1 and the climate chamber according to the preamble of Claim 13 in such a way that not only are the products treated uniformly relative to one another but also the uniform treatment of each product separately is further improved, in particular made more homogeneous.
  • the aforementioned object is achieved in that the direction in which the gas stream is circulated through the circuit is reversed repeatedly, in each case once a reversing time interval has elapsed.
  • the gas displacement device is provided with a reversing system configured for reversing repeatedly, in each case once a reversing time interval has elapsed, the direction in which the gas stream is circulated through the circuit.
  • Regularly (meaning both at fixed time intervals as well as at variable time intervals) and repeatedly changing the direction in which the gas stream is circulated through the circuit means that the passing gas stream flows through the product placed in the compartment in each case from a different, opposing side.
  • the length of the reversing time interval can in this case remain constant over the entire treatment time or over a portion of the treatment time, in which case the direction in which the gas stream is circulated is thus reversed periodically, although this reversing time interval can also be variable. It may be conceivable to provide on one or more products sensors which activate the reversing of the gas stream as a function of measured values.
  • the reversing time interval will depend on the product to be treated. Generally, the reversing time interval will be less than 2.5 hours (i.e. the gap between one reversing action and a subsequent reversing action will be less than 2.5 hours); more particularly, the reversing time interval will generally be less than 1 hour.
  • the reversing time interval will be at most 30 minutes, preferably at most 20 minutes. Taking account of the delays which play a part in the treatment process, such as the temperature gradient of the product to be treated, the delayed response of used heat exchangers and the delayed response mass of gas which is circulated, the reversing time interval will in practice be at least 1 minute, preferably at least 5 minutes, more preferably at least 7.5 minutes. With regard to the hatching-out of eggs, the direction of the gas stream will reverse over at least 4 to 10 hours, for example over 1 to 4 days or longer, advantageously at a fixed or variable reversing frequency, and in particular from the start of the treatment.
  • the reversing, after a respective reversing time interval, of the direction in which the gas stream is circulated can, if appropriate, be terminated if it serves no further purpose.
  • the gas stream passes through the compartment predominantly from one lateral wall to the other lateral wall.
  • a gas stream having predominantly one clear direction is thus obtained in the compartment.
  • the opposing lateral walls are configured as a perforated plate provided with a fluid pipe through which a fluid is conveyed, in such a way that each lateral wall forms a heat exchanger with which the temperature of the gas stream passing through said lateral wall can be influenced.
  • the temperature of the gas stream entering the compartment can be regulated very accurately and, on the other hand, it is possible - by means of the perforations - to cause the gas to enter the compartment in a very uniformly distributed manner or, by contrast, distributed according to a specific pattern.
  • the compartment is divided in the direction of flow into at least two successive subcompartments, if adjacent subcompartments are each separated from one another by a partition wall configured as an aforementioned perforated plate provided with a fluid pipe through which a fluid is conveyed, in such a way that the partition wall forms a heat exchanger with which the temperature of the gas stream passing through the partition wall is influenced, and if the partition wall extends substantially transversely to the direction of flow of the gas stream through the compartment.
  • partition walls then allow, in each case at the end of a subcompartment, the gas stream to be brought back to a specific desired temperature, thus allowing cooling or heating of the gas stream when passing through the subcompartment to be compensated for.
  • a compartment of this type which is divided into subcompartments and has dividing walls configured as heat exchangers and also opposing lateral walls of the compartment in the form of heat exchangers, is known from EP 1 104 987 and from the Applicant's application PCT/NL 2007/050370 (application number) which was filed on 13 July 2007 and describes an inventive improvement to heat exchangers of this type.
